That Os Mutantes' edgy brand of psychedelia and Tropicalia continues to get big ups from today's hipster nation (after being championed for years by everybody from Kurt Cobain to Beck to David Byrne) is testimony to the unbending passion in their music.

The seminal Brazilian band, which last year signed to Anti- Records and released its first album in 15 years, Haih or Amortecedor, have spent the bulk of 2010, including dates earlier this month at Austin's Fun Fun Fun Fest and a U.S. jaunt with Ariel Pink's Haunted Graffiti that ends tonight in L.A., where Os Mutantes will step aside and let Ariel Pink headline his hometown show.

No mistake, though, that much respect is due, not only for the music for the persevering as artists during troubled times in their native country. Frontman Sergio Dias recently took a look back in an interview with the BBC. Recommended.

After the jump, a similarly tasty piece from Os Mutantes' 2006 visit to the Pitchfork Music Festival:
